ROBERT MATTHIES AND JOHN A. SHEPHERD, OF HAMMOND, INDIANA.

DUMP-BOX.

Application filed December 24, 1913.

To all whom it may concern:

Be it known that we, ROBERT MATTHIES and JOHN A. SHEPHERD, citizens of the United States, residing at l'lammond, in the county of Lake, State of Indiana, have invented a new and useful Dump-Box, of which the following is a specification.

In this application there is disclosed a dumping wagon of that general type shown in our prior Patent No. 1,022,562, and the present application divulges divers improvements in the structure set forth in the patent above mentioned.

The device forming the subject matter of this application is a dumping wagon, and one object of the present invention is to provide novel means for releasing the levers which, being operatively connected with the doors of the dumping wagons, constitute means for maintaining the doors in closed position.

Another object of the invention is to provide novel means whereby the flexible elements which control the doors may be operatively connected with the arms of the actuating shafts. It is within the scope of the invention to improve generally and to enhance the utility of, devices of that type to which the present invention appertains.

lVith the above and other objects in View which will appear as the description proceeds, the invention resides in the combina tion and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the in vention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawing:Figure 1 shows in end elevation, a dumping wagon embodying the present invention parts being broken away and sectioned: Fig. 2 is a side elevation of a dumping wagon box embodying the present invention parts being broken away; Fig. 3 is a detailed view illustrating the means whereby the door controlling levers are released.

In the accompanying drawing, the numeral 1 indicates the box of a dump wagon, the box being of any desired construction. The box 1 in the present instance includes a longitudinal sill 2 to which doors 3 are hinged. Hangers 4 are applied to the side walls of the wagon body, the hangers 4 sup- Specification of Letters Eatent.

porting doors 5 which cooperate with the doors 3 as will be understood readily from Fig. 1. Chains or other flexible elements are secured at their inner ends to the sill 2 and extend beneath the doors 3 and 5, in opposite directions. Mounted upon the doors 3 and 5 are brackets 7 across which the chains 6 pass.

Shafts 8 extend longitudinally of the sides of the box 1, the shafts 8 being journaled for rotation in bearings 9 upon the sides of the box. The shafts 8 are provided with any desired number of arms 10, located in pairs. J ournaled in the arms 10 adjacent their free ends is a shaft 11 through which passes a support, preferably taking the form of an eye bolt, there being nuts on the eye bolt to engage opposite sides of the shaft 11. The upper ends of the flexible elements 6 are connected with the eye bolts 12.

Secured to the forward end of each shaft 8 is a lever 15 mounted to swing transversely of the forward end of the wagon box. Arms 16 project laterally from the forward end of the wagon box 1, beyond the side walls thereof, the arms terminating in bookshaped stops 17. These stops 17 cooperate with the levers 15, to limit the outward movement of the levers. when the doors 3 and 5 drop to open positions as shown most clearly on the left hand side of ig. 1.

Secured to the front wall of the wagon box 1 are upright bars 18 which may be angle members. Detent lugs 19 are secured to the bars 18 and project beyond the forward edges thereof, the lugs 19 being beveled upon their forward edges as clearly shown in the drawings.

Projecting from the forward wall of the box 1 is a foot board 20 upon which may be superposed a top plate 21, provided along its edges with bearings 22 in which is mounted a transverse shaft 23 carrying at its ends trip levers 24. each trip lever 24 terminating at one end in a foot plate 25 and terminating at the other end in a hookshaped extension 26. adapted to engage behind the corresponding lever 15.

When the doors 3 and 5 are in a closed position. as shown on the right hand side of Fig. 1, the chains 6 are drawn upwardly by means of the arms 10, the shaft 8 being rotated by means of the lever 15, and the lever 15 moving inwardly and downwardly adjacent the forward edge of one bar 18, until the lever engages beneath the detent lug 19. In this manner, the doors 3 and 5 will be locked in closed positions.

It is to be observed that the hoolosliaped extension 26 of the trip lever 24 engages behind the lever 15. If the foot of the opera-- tor be placed upon the foot plate 25 and if the trip lever 24 be swung upon its fulcrum 23, the hook-shaped extension 26 of the foot lever will engage behind the corresponding lever 15 and swing the lever 15 forwardly, so that the same no longer is engaged beneath the corresponding detent lug 19. Then, the weight of the contents of the box 1, resting upon the doors 3 and 5 will cause the doors 8 and 5 to move to an open position as shown onthe left hand side of Fig. 1. The shaft 8 will be rotated and the lever 15 will swing laterally and outwardly, the outward movement of the lever 15 at its free end being limited by the engagement of the lever 15 and the hook shaped stop 17 on the end of the arm 16. Owing to the fact that supports or eye bolts 12 are held in the shafts 11 by means of the nuts 14, the eye bolts may be moved longitudinally, thereby to adjust the tension of the chains 6. The shafts l1 rotate in the arms 10 and therefore, during the operation of the structure, there is no tendency to flex the eye bolts 12 transversely, the only strain upon the eye bolts being in the direction of their lengths.

Having thus described the invention, what is claimed is:

1. A dumping wagon comprising a box; a door movably connected with the box; a flexible element operatively connected with the door; a shaft supported for rotation upon the box, the flexible element being connected with the shaft; a lever connected with the shaft; a fixed detent on the box, with which detent the lever is adapted to engage; and a trip lever supported adjacent the box, the trip lever being adapted to engage and bear directly upon the first specified lever to move the same transversely of its plane of swinging movement thereby to free said lever from the detent.

2. A dumping wagon comprising a box; a shaft journaled for rotation on the box; a lever secured to the shaft; a detent on the box with which the lever is adapted to cooperate; a trip lever supported for movement with respect to the box and including a hook-shaped extension engaged behind the first specified lever to free the same from the detent when the lever is moved; a door mounted to swing with respect to the box; and means for operatively connecting the door with the shaft.

3. A dumping wagon comprising a box; a shaft journaled for rotation on the box; arms projecting from the shaft; a second shaft journaled for rotation in the arms; a support mounted on the second shaft adjustably; means carried by the support and engaging the second shaft to hold the support in adjusted positions; a door connected with the box; and means for connecting the door with the support.

4. A dumping wagon comprising a box; a shaft journaled for rotation on the box; arms secured to the shaft; a second shaft journaled for rotation in the arms; an eye bolt passing through said shaft; nuts on the eye bolt engaging the opposite sides of the second shaft; a door pivotally connected with the box; and means for operatively connecting the door with the eve bolt.

In testimony that we claim the foregoing as our own, we have hereto affixed our signatures in the presence of two witnesses.
